Floating Social - Plugin

Hello, I'm having problems with the floating social plugin. I can't manage to keep it constatnyl on the side of tha page. As it is right now, it moves when depeding on screen size and such. And if I use left-horizontal-text it changes everytime I'm on a page that hasnt text on the side.

So my question comes down to:
How do I i make the plugin to stay constantly on the side of the page, exactly next to the boxed page.

For example look at the page: "Tjänster"
